Description

BACKGROUND OF THE INVENTION

1. Technical Field

The present invention relates to a connector, and more particularly, to a connector with water-proof capability.

2. Description of Related Art

Connectors have been extensively used in various industries as well as mechanical and electrical apparatuses to allow users to therethrough rapidly transmit data, signals and electric power as desired. The advent of connectors speeds up receipt of data and makes people's daily life more conveniences.
Connectors are widely applicable, and many applications thereof in our daily life need connectors to be exposed in the atmosphere. Since a connector implements conductive terminals as contacts for electrical connection, two coupled connectors without any water-proof structure therebetween are likely to, due to damp or moisture, have a short circuit that may destroy the transmission of the connectors and make the connectors unusable.
In addition, two coupled connectors without any reinforcing structure therebetween for securing the connection are likely to be disconnected under an external impact and have the transmission accidentally interrupted. As an even worse consequence, electric leakage may take place between the connectors and bring a user who touches the terminals with the risk of an electric shock or other accidents.

SUMMARY OF THE INVENTION

To overcome the shortcomings of the prior arts mentioned above, the present invention provides a water-proof connector assembly. The water-proof connector assembly comprises a first connecting device, a second connecting device and a fastener, wherein the first connecting device, the second connecting device and the fastener are assembled along a predetermined axis. The first connecting device includes a first casing, a male conductive terminal, a water-resisting member and a first screwing member. The second connecting device includes a second casing, a female conductive terminal, a second water-proof sleeve and a second screwing member. The aforementioned first casing, the second casing and the fastener are all tubular in shape.
The first casing has a first inner hole extending along the above-mentioned predetermined axis. The first casing is provided with successively a first section, a second section, a third section and a fourth section along the predetermined axis. The second section is sunken inwardly to form a pair of recessed portions. The first section has a pair of through holes extending along the predetermined axis. Each of the pair of through holes passes through each of the pair of recessed portion through a pair of first openings. The pair of recessed portions are further provided with a pair of first retaining areas, which are disposed at a pair of outer sides of the pair of first openings.
The second casing has a second inner hole extending along the above-mentioned predetermined axis. The second casing is provided with successively a fifth section, a sixth section and a seventh section along the predetermined axis. The fifth section engages with the first inner hole of the first casing. The second casing further comprises a pair of retaining arms, which are extended from a top of the sixth section along the predetermined axis and located outside the fifth section. The pair of retaining arms have a pair of terminals projecting outwardly to form a pair of projecting portions. The pair of projecting portions have a pair of second retaining areas formed at a side adjacent to each of the pair of retaining arm. Each of the pair of projecting portions passes through each of the pair of through holes of the first casing to engage with each of the pair of recessed portions.
The fastener has a third inner hole extending along the above-mentioned predetermined axis. The fastener is mounted around the first section and the second section of the first casing, thereby the fastener is movable on a first outer surface of the first section and the second section between a predetermined first position and a predetermined second position. In addition, the fastener has a pair of tongues extending along the predetermined axis. Therefore, when the fastener is located at the predetermined first position on the assembled first connecting device and the second connecting device, each of the pair of tongues is positioned below each of the pair of projecting portions of the second casing. When the fastener is located at the predetermined second position, each of the pair of tongues is no more positioned below each of the pair of projecting portions of the second casing.
Accordingly, the primary object of the present invention is to provide a water-proof connector assembly. The water-proof connector assembly comprises a first connecting device, a second connecting device and a fastener. The first connecting device includes a first casing, which has a first section, a second section, a pair of recessed portions and a pair of first retaining areas. The second connecting device includes a second casing, which has a pair of projecting portions and a pair of second retaining areas. The fastener has a pair of tongues and is mounted around the first section and the second section of the first casing. The fastener is movable on a first outer surface of the first section and the second section between a predetermined first position and a predetermined second position. Therefore, when the fastener is located at the predetermined first position on the assembled first connecting device and the second connecting device, each of the pair of tongues is positioned below each of the pair of projecting portions of the second casing. Besides, each of the pair of second retaining areas of each of the pair of projecting portions contacts with each of the pair of first retaining areas of the first casing. Hence, the water-proof connector assembly of the present invention implements the fastener to secure connection between the first connecting device and the second connecting device, which is unlikely to loose or be taken apart due to external impact or unintentional force, so as to ensure durable electrical conductivity of the water-proof connector assembly.
Another object of the present invention is to provide a water-proof connector assembly. The water-proof connector assembly comprises a first connecting device, a second connecting device and a fastener. The first connecting device includes a first casing, which has a first section, a second section. The first section has a pair of second retaining holes. The second connecting device includes a second casing, which has a sixth section. The sixth section has a pair of first retaining holes. The fastener further includes a pair of teeth extruded inwardly from a wall of the third inner hole. The fastener is mounted around the first section and the second section of the first casing. The fastener is movable on a first outer surface of the first section and the second section between a predetermined first position and a predetermined second position. When the fastener is located at the predetermined first position, each of the pair of teeth engages with each of the pair of first retaining holes. Hence, the water-proof connector assembly of the present invention implements the fastener to secure connection between the first connecting device and the second connecting device via the pair of teeth, which is unlikely to loose or be taken apart due to external impact or unintentional force, so as to ensure durable electrical conductivity of the water-proof connector assembly.
Yet another object of the present invention is to provide a water-proof connector assembly. The water-proof connector assembly comprises a first connecting device, a second connecting device and a fastener. The first connecting device includes a first casing, which has a first section, a second section. The first section has a pair of second retaining holes. The second connecting device includes a second casing, which has a sixth section. The sixth section has a pair of first retaining holes. The fastener further includes a pair of teeth extruded inwardly from a wall of the third inner hole. The fastener is mounted around the first section and the second section of the first casing. The fastener is movable on a first outer surface of the first section and the second section between a predetermined first position and a predetermined second position. When the fastener is located at the predetermined second position, each of the pair of teeth engages with each of the pair of second retaining holes so that the fastener uses the pair of teeth to firmly hold the first section and the second section of the first casing without hindering the connection between the first connecting device and the second connecting device.
Still another object of the present invention is to provide a water-proof connector assembly. The water-proof connector assembly comprises a first connecting device, a second connecting device and a fastener. While the first connecting device has a first water-proof sleeve, the second connecting device has a second water-proof sleeve. Therefore, in virtue of the first water-proof sleeve and the second water-proof sleeve, damp or moisture is blocked from entering the first connecting device and the second connecting device, thereby improving the water-proof connector assembly in water-proof ability and service life.

Please refer to FIG. 3, which is a cross-sectional view of the assembled first connecting device 1 and second connecting device 2 taken along the predetermined axis A according to the first preferred embodiment of the present invention. Particularly, each of the pair of projecting portions 216 passes through each of the pair of through holes 117 of the first casing 11 to engage with each of the pair of recessed portions 116.
Still referring to FIG. 3, the above-mentioned male conductive terminal 12 is disposed in the first casing 11 while the above-mentioned female conductive terminal 22 is disposed in the second casing 21. Thus, when the first connecting device 1 and the second connecting device 2 are assembled, the fifth section 211 of the second casing 21 engages with in the first inner hole 115 of the first casing 11. Thereby, the female conductive terminal 22 in the second casing 21 allows the male conductive terminal 12 in the first casing 11 to be inserted thereto, so as to conduct electricity.
Please refer to FIG. 1, FIG. 3 and FIG. 4. FIG. 4 is a cross-sectional view of the fastener 3 taken along the predetermined axis A according to the first preferred embodiment of the present invention. The fastener 3 has a third inner hole 31 extending along the predetermined axis A. Particularly, the fastener 3 is mounted around the first section 111 and the second section 112 of the first casing 11, thereby the fastener 3 is movable on a first outer surface (not shown) of the first section 111 and the second section 112 between a predetermined first position P1 and a predetermined second position P2. In addition, the fastener 3 has a pair of tongues 32 extending along the predetermined axis A. Therefore, when the fastener 3 is located at the predetermined first position P1 on the assembled first connecting device 1 and the second connecting device 2, each of the pair of tongues 32 is positioned below each of the pair of projecting portions 216 of the second casing 21. Besides, each of the pair of second retaining areas 217 of each of the pair of projecting portions 216 contacts with each of the pair of first retaining areas 119 of the first casing 11.
